A strategic plan for innovation is an essential tool for any academic institution. This disruptive strategic plan for innovation maximizes the value and benefits for public and private institutions using the logical framework and the house of quality. With the logical framework of action, the input data for planning is clear, the rest of the activities of the house of quality (product design, process design and process control) are direct. The house of quality is the most effective technique to understand and even quantify the value of proposals. In addition, applied to a university, it ensures the obtaining of funds (money) that support and promote the development of innovation by prioritizing the voice of the customer (Innovate).

This paper analyzes the production indicators for the period 2000-2020 of the Peruvian Institute of Nuclear Energy, an institution that researches and applies knowledge of ionizing radiation. The research institute published an average of one article per year between 1984 and 2000. During the period 2001 to 2006, some policies were applied. Staff salaries were tripled, allowing the incorporation of researchers with experience in scientific research. The number of publications increased from 01 in 2001 to 15 in 2007 as a result of intense work done in 2006. These policies were ignored in 2007 with a significant change in research productivity in years to come. Finally, an overall analysis determines that: (a) management actions are different from manager director to manager director and the changes substantially affect research productivity, (b) the policy that increases researcher salary...

Anatomical, histological, and developmental testicular changes from birth to puberty were studied in 80 Japanese quails. Ten birds per week were body weighed and slaughtered to measure the testis. Testicular tissue samples were collected and evaluated. Body weight varied from 35 g at week 1 to 180 g at week 8. The length of the testis varied from 0.1 mm at week 1 to 8 mm at week 8. The presence of Leydig cells coincided with the appearance of secondary sexual characteristics at week 7. Spermatozoa in the seminiferous tubules were not observed, even by the end of week 8.

Morphological changes of the ovary and oviduct from birth until sexual maturation were monitored in 35 female quails. The birds were randomly selected from a flock reared at the quail farm of the Facultad de Medicina Veterinaria de la Universidad Nacional Mayor de San Marcos. Five quails were weighed and then slaughtered every week starting at one week of age. The ovaries were measured in situ, removed and processed for histological evaluation. Mean body weights and ovary length were 40, 68, 108, 132, 138, 171, and 154 g; and 6.9, 8.8, 11.6, 12.0, 11.8, 13.3, and 13.3 mm for the 1st, 2nd, 3rd, 4th, 5th , 6 th, and 7th week of age. Sexual maturity started at week 6. Histological images of growing and mature follicles coincided with macroscopic observations.

The present work evaluated the mortality, removal, and discarded rates in broilers of two commercial genetic lines, reared in three consecutive cycles of 45-49 days each under similar management conditions. In each cycle, 360 birds per genetic line (A and B) were used. Necropsy was carried out to dead and removed birds. Removed birds were those that showed severe growth delay and discarded birds were those that showed injuries or abnormalities at the end of the cycle. In both lines, the main causes of mortality were the ascites syndrome and sudden death syndrome. Line B showed higher mortality rate during the first cycle (p<0.05), but there was no statistical difference in the removal and discarded rates between the two genetics lines. The main cause for removing birds in both lines was leg problems, mainly chondrodystrophia. In general, it can be concluded that productive performance...

The purpose of the study was to evaluate the effect of yacon meal as a prebiotic in rations for Muscovy ducks. One hundred and fifty male ducks of seven weeks of age were used. The ducks were grouped in five treatments: T0, control (without yacon and antibiotic); T1, zinc bacitracin 0.035%; T2, T3 and T4, yacon meal at 0.25, 0.50 and 0.75% respectively. Treatments T1, T2 and T4 resulted in higher body weight gain as compared to T0 (p<0.05). No differences were observed between treated groups and T0 on feed consumption. Feed conversion index was significantly better in T1, T3 and T4 as compared to T0 (p<0.05). The cost of feed per unit of body weight gain was lower in T1, T2, T3 and T4 as compared to T0. The inclusion of 0.75% of yacon meal in the diet would be an alternative to the use of antibiotics in rations of ducks during the fattening phase.

A fin de determinar el efecto del Montelukast sódico, un bloqueador de leucotrienos, sobre la presión arterial pulmonar media, que se encuentra incrementada en aves con síndrome ascítico, se estudiaron 60 pollos de producción de carne, machos, de la línea Arbor Acres, nacidos y criados hasta los 35 días de edad a nivel del mar. A los 30 días de edad fueron divididos en dos grupos de 30 aves cada uno: grupo Control y grupo Tratado que recibió 0.2 mg/ kg de peso vivo de Montelukast sódico, vía oral, diariamente, durante cinco días consecutivos. A los 35 días de edad, a todas las aves se les determino la Presión Arterial Pulmonar media (PAPm), Hematocrito (Ht) y Peso Corporal (PC). La PAPm se efectuó mediante cateterismo directo en la arteria pulmonar izquierda mediante la técnica descrita por Burton, utilizando un transductor de presión conectado a un sistema de registro. ...

The study aimed to compare the body weight, and cardiac indices, hematocrit and hemoglobin as indicators of cardiac activity of two turkey commercial lines reared at sea level. Thirty five turkeys from each line were used in the study. Body weight (PC) was recorded from the 4th to the 14th week of age where birds were slaughtered. There, blood samples were collected for measuring hematocrit and hemoglobin levels. Also, hearts were collected to determine the following ratios: weight of right ventricle/total ventricle (VD/VT), weight of left ventricle/total ventricle (VI/VT), weight of left ventricle + septum/ total ventricle (VI+S/VT), VI/PC, VD/PC, VI+S/PC, and VT/PC. Body weight and haemoglobin in BUT turkeys were higher (p<0.05) and hematocrit was higher (p<0.05) in Hybrid turkeys. No statistical differences were found on VD/VT, VI/VT, (VI+S)/VT, and VD/PC between lines, but high...

The Strategic Research Plan (PEI) is an essential tool, which defines roles and sets of actions that any Academic Institution must carry out. One of the priorities for academic organizations and especially for universities, is the formation of human capital. That training must develop the research and innovation capabilities of its graduates, to create, generate ventures, transfer and apply new knowledge. Various techniques can be used to prepare the PEI; however, Quality Function Deployment (QFD) includes the voice of the customer and is very effective for developing a PEI. With the use of the QFD it was obtained: the lines of investigation, the processes of planning, design, monitoring and control based on the requirements of CONCYTEC (the voice of the client). Finally, a PEI aligned with the CONCYTEC requirements is justified, thus increasing the possibilities of being able to obtain ...
